A modified single flap for neck dissection in oral cancer.
Modification of the single flap for neck dissection is described and illustrated based on experience with 33 cases of squamous cell carcinoma of the oral cavity. The advantages of this modified incision are that there are no three-point junctions. Hence, it can be used after previous radiotherapy to the neck; the vertical limb is well posterior to the carotid artery, and the horizontal limb can be conveniently extended upward and forward to permit a combined resection of the jaw and/or tongue. To avoid necrosis at the apex of the skin flap, particularly after previous radiotherapy, a margin of about 1 cm can be removed prophylactically from the apex. This incision is recommended particularly for neck dissections in squamous cell carcinomas of the oral cavity in patients who have had previous radiotherapy and/or when resection of the mandible or the tongue is to be done at the same time. The incision is not recommended for bilateral neck dissections, nor for neck dissection combined with total laryngectomy or thyroidectomy.
